Add a quirk XHCI_ZHAOXIN_HOST for zhaoxin xhci to fix issues, there are two cases will be used. - add u1/u2 support. - fix xHCI root hub speed show issue in zhaoxin platform. Add a quirk XHCI_ZHAOXIN_TRB_FETCH to fix TRB prefetch issue. On Zhaoxin ZX-100 project, xHCI can't work normally after resume from system Sx state. To fix this issue, when resume from system Sx state, reinitialize xHCI instead of restore. So, Add XHCI_RESET_ON_RESUME quirk for ZX-100 to fix issue of resuming from system Sx state.

I'd split this series into different logical parts: patch 1/4 Set XHCI_RESET_ON_RESUME quirk to ZHAOXIN host to fix resume issue. cc: stable patch 2/4 Add XHCI_ZHAOXIN_TRB_FETCH quirk flag together with code that allocates double pages cc: stable patch 3/4 Add XHCI_ZHAOXIN_HOST quirk flag together with code that corrects USB3 roothub minor version cc: stable patch 4/4 Set XHCI_LPM_SUPPORT quirk together with code that sets tier policy and u1/u2 timeouts, Don't add stable as this is about adding feature support. (Accidentally replied to older v2 series with the above comments) Thanks -Mathias
